IMPROVEMENT IN STEAM-GENERATORS.

The Schedule referred to in these Letton Patent and making put' o! thelame.

To all 'whom it may concern:

Be it known that I, JONATHAN M. CLARK, of the city, county, and State ofNew York, have invented certain new and useful Improvements inSteam-Geu- -erators, of-which the following is a full, clear, and exactdescription, reference being had to the accom- "panying drawing throughletters of reference marked thereon, and in which- Figure 1 representsan end view of a portion of a generator' embracing my improvement.

Figure 2, a longitudinal section through the line a: on tig. 1.v

The sauro letters indica-te like parts on both figures.

The object Aof this invention is to provide for the more convenientconnection of the, heads at each end of trhe'pipes, and the production.of a better circulation therethrough; and

It consists in forming tubular connections to bc screwed into the twoadjacent hczuls'hwith lock-nuts outside of the latter; also in thearrangement of the lateral connection at the feed-end of the pipes, asnear the bottom of the head as possible, and at thc upper or steam endas near the top as possible.

Referring to the drawing- A represents the pipes of steam-generator,which are arranged side by side, and in tiers one above another in azigzag or alternate manner, so that the pipes in one row, horizontally,shall be vertically intermediate of those in each adiacenti row, and areal.

so arranged on a-slight incline, longitudinally, 'as represented in fig.2.

The heads B may be cast separate, and wronghtiron or other pipesconnected in any suitable manner,

or the pipe, with its two heads', may be cast in one prece.`

'These are tuen connected by L-pieces C, screwed into each threeadjacent pipes throughout the entire tier, and the joints made steam andwater-tight by lock nuts D. They may be put together with right andvlett-hand screws, or all right-hand, in the latter case they must befirst `screwed double their proper distance into one head and thenbacked out and into the other one.

Byarranging the lateral connection at the lowest point o f the low endof the range the water has" a better circulation, and its arrangement atthe highest point at t-lre opposite end gives a freer escape for thesteam upwardly as it is generated. s

What is here claimed as new, and desired to be securedby Let-tersPatent, s-

The L-tbrmcd tubular' connection C, in combination with the lock-nuts I)and heads B, substantially as shown and described.

2. lhe arrangement'of the lateral tubular connections nearl the bot-tornof the. heads at the one end of the pipes A, and near 'their .top at theother end of the said pipes, as setforth.
